Explanation:
Given
-- Mass of the boy
-- Mass of the girl
-- Acceleration of the girl towards the boy
Required
Determine the acceleration of the boy towards the girl ()
From the question, we understand that the surface is frictionless. This implies that the system is internal and the relationship between the given and required parameters is:
Substitute values for and
Make the subject
<em>Hence, the acceleration of the boy towards the girl is 1.446m/s^2</em>
Answer: 44 N/m
Explanation:
Finding the interatomic spring stiffness
Because in our model all the bonds are assumed to be the same, the interatomic spring stiffness ks, interatomic is determined by adding the springs . The details of that addition are below, but the final result is that the interatomic spring stiffness is related to the spring stiffness of the wire like so:
